STELLAR EVOLUTION IN THE LIGHT OF RECENT RESEARCH.*
PROFESSOR GEORGE E. HALE
MANY attempts have been made to sum up the work of the nineteenth century, and to define its principal lines of progress. In estimates of the relative importance of the books published during this period there has been some divergence of view, but regarding one of them no element of doubt seems to have entered the minds of the critics.
OF the cold-blooded, air-breathing animals known as true reptiles there are now in existence upon the globe more than four thousand species, classified by naturalists in four very distinct groups or orders—the Rhynchocephalia, Crocodilia, Chelonia and Squamata.
THE sudden appearance of certain familiar birds in spring and their disappearance at the close of summer has excited the attention and interest of all classes of observers from the earliest times. “The stork in the heaven,” says the prophet Jeremiah, “knoweth her appointed time; and the turtle and the crane, and the swallow observe the time of their coming.”
THERE is a sense in which human environments may be viewed in their relation to sex. The greater part of the earth’s surface was sterile to all primitive peoples, anterior to the times when the harnessing of physical forces, little by little, brought all lands and all waters under human dominion.
IN the twentieth century the college-man is, more than ever before, the leader of the world. Mind leads the world; mind ultimately is the ruler of the world. That mind leads the world which is not simply developed into maximum intellectual perfection ; it is that mind which, perfected and strengthened and given symmetry and vigor, is also made most thoroughly at one with the world.
THE negro’s real menace to the South lies in the paucity of his earthly wants. His few demands upon the world can be met with little exertion, and the outgrowth of his indolence is vice and crime. Generations of slavery have crushed out the spirit of accumulation.
GENEEAL evolutionary evidence led anthropologists some time ago to postulate a pliocene precursor of man, but their surmise has only recently been substantiated by particular proof. The search for the so-called missing link was at first confined to the temperate zone.
To the Editor:—Professor E. Ray Lankester, director of the Museum of Natural History, London, concluded an address on ‘The Scope and Functions of Museums’ at the opening of a new wing of the Ipswich Museum on November 8 with the following words:
THE ‘Dictionary of Philosophy and Psychology,’ edited by Professor J. Mark Baldwin and published by the Macmillans, is a work of magnitude and importance. Only one of the three volumes has as yet been issued, but it suffices to give a correct impression of the character, range and quality of the undertaking.
ONE of the most noteworthy events in the history of science was the bequest of James Smithson, an Englishman dying in Italy, in 1829, of about $500,000 to found at Washington ‘an establishment for the increase and diffusion of knowledge among men.’
